Application filed November 6,1914. Serial No. 870,548.

T 0 all whom it may concern Be it known that we, WVALTER M. Soo'r'r and RALEIGH E. TRESISE, citizens of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio,

have invented new and useful Improvements in Battery-Meters, of which the following to simplify the construction and economize the production of the frames upon which the operating parts or working elements of such meters are mounted, as well as to facilitate the assembling of such working parts We realize such object by constructing the frame in such manner that certain of the spacing and supporting devicesand preferably all of themare made integral with the frame. By so constructing the frame, we have obviated a number of the operations heretofore considered necessary to the production of the spacing and supporting means and to the assembling of the working elements, such production and assembling heretofore involving the production of a plurality of separate members; and

our invention has resulted in producing themeters, not only in a more economicalmanner, but. in providing a more compact and reliable construction.

The annexed drawing and the following description represent means illustrating one type of our invention, such disclosed type representing, however, but one of the possible ways in which the spirit of our invention may be utilized.

in said annexed drawing: Figure 1 represents a front elevation of an assembledmeter of the volt-ammeter type embodying our invention; Fig. 2 represents a rear elevation of a meter of the ammeter or volt-meter type, also embodying our invention, the rear of the case being removed; Fig. 3 represents afront elevation of our improved frame as it would appear if flattened out, showing 1n dotted lines the cuts or incisions that are made in the blank from which it is formed to provide the elements from which the several members embodied in the frame are formed up; and Fig. 4. shows a perspective view of the formed up frame, there being shown therein the location of the indicatorpolnter with reference to the coil-supportmg member.

Referring to the annexed drawing, 1 represents the case of .our improved battery meter provided with the binding post 2 and the terminal 3. The meter is provided with a flexible copper wire cable 4: shown in Figs. 1 and 2. The peripheral wall of the case 1 is punched to provide small lugs 5 and 6 adapted to assist in retaining the integral frame 8, hereinafter referred to, securely in the casing 1; as, also, prevent the rear of the case being shoved too far into said wall. The permanent control of the meter, or the element which exerts the permanent directive influence upon the same, is magnet 7.

The integral, one-piece frame, shown at 8, is adapted to be a general'supporting member for all the working elements of the meter and to form in connection with a the terminal 3. This entire frame 8 is formed up from a one-piece blank in opprovide a pivotal support for an indicator pointer 15, are formed up in the lower por-- tion of the frame 8. The' coil-supporting member 12 is shown as a spool, but the two members 16 and 17, Fig. 3, could be much shorter thus providing a coil-supporting portion which would be practically flat instead of a spool formation. The indicator pointer 15 plays through the spool 12, as shown in Fig. 4, and has an armature portion 18, as shown in Figs. 2 and 4.

A cable 19 forming electrical connection small part of which is exposed as shown Our improved meter can be used either as an ammeter, a volt-meter or both, and we wish particularly to lay stress upon the fact that the whole supporting frame of the instrument is formed up economically,

into a very strong and compact light-weight construction, and in its preferred embodiment from a one-piece blank which is ab solutely integral.

Having thus described our invention, what we claim is:

1. In a battery meter, a formed-up integralframe comprising a substantially semicircular upper portion adapted to support the element which exerts permanent directive influence upon the meter, and an irregularly shaped lower portion formed into a spool. i

:2. A formed-up integral frame for the purposes described, comprising a portion adapted to form a magnet support and a portion about which a coil may be wound, said latter portion adapted also to form a pointer support.

3. A formed-up integral frame for-the purposes described, comprising an upper portion formed up to carry a magnet and a lower portion formed up to provide a spool and to carry a pointer.

4. A. formed-up integral frame for the purposes described, comprising a supporting car, a magnet-supporting portion, a spool, and pointer-supporting means.
